Opportunities to expand mineral resource along strike and at depth with additional drilling

The resource estimate was prepared by Mr. Allan Reeves. Mr. Reeves is a Professional Geologist and independent Qualified Person (QP) as defined by N.I. 43-101 Standards of Disclosure for Mineral Projects. He has over 35 years of industry experience and spent 23 years at BHP Billiton where he held senior-level positions at both the Ekati Diamond Mine and Island Copper Mine.

Notes:

Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all, or any part of the Mineral Resources estimated will be converted into Mineral Reserves.

The LG constrained shell economics used a mining costs of US$6.25, processing costs of US$129.41/tonne and a commodity price of US$400.00/tonne 95%MgO DBM.

Mineral resources are reported within the constrained shell, using a cut-off grade of 42.5% MgO (based on 40 years) to determine ‘reasonable prospects for eventual economic extraction’.

Tonnages are reported to the nearest 1,000 tonnes, and grades are rounded to the nearest two decimal places.

Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade and contained metal.

The resource estimate was prepared in accordance with Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Standards on Mineral Resources and Mineral Reserves as adopted by the CIM Council.

An updated technical report on Driftwood Creek, including the new resource estimate, will be filed on SEDAR within 30 days.

Project BackgroundMGX Minerals has the right to acquire a 100% interest in Driftwood Creek. The project is located 164 kilometers north of Cranbrook, British Columbia and is accessible by a network of maintained logging roads. The Company has conducted two rounds of diamond drilling at Driftwood Creek and recently completed a 100-tonne bulk sample program (see press release dated June 9, 2016). MGX received a 20-year Mining Lease for Driftwood Creek in January (see press release dated January 11, 2016).

Pilot Plant MillThe Company is in the process of transporting and assembling a pilot plant mill (the “Mill”) at the current stock-pile location of the recently completed 100-tonne bulk sample (see press release dated June 9, 2016). The Mill equipment includes a jaw crusher, ball mill, flotation cells, cyclone dewatering equipment and a tailings filtration and thickener system. Previously the Mill was utilized to process polymetallic concentrate. MGX intends to process mineralized bulk sample material through the Mill using reverse flotation to produce two products- a high purity magnesite tailing and silica sand float byproduct. The magnesite (MgCO3) material will then be shipped off site to undergo calcination optimization testing to produce magnesium oxide (MgO) as well as thermal and electrolytic analysis to produce magnesium metal (Mg).

MetallurgyExtensive metallurgical and process design work was previously completed on mineralized material from Driftwood Creek by SGS Lakefield (“SGS”). The process design developed by SGS closely follows the current flowsheet plans for the pilot plant mill, inclusive of the reverse flotation and tailings dewatering system, to produce high grade magnesite concentrate. Pilot plant testing will allow the Company to further optimize grinding, milling and flotation elements to develop a finalized process flow.

MagnesiumMagnesium (Mg) is a non-metallic abundant alkaline earth metal that represents an important material for today’s modern lifestyle- smartphones, automobiles, aircrafts, and other everyday essentials all require magnesium. Magnesium’s unique characteristics make it 75% lighter than steel and 33% lighter than aluminum while still offering comparable strength-to-weight ratios. Magnesium is the third most used structural metal (behind iron and aluminum) and considered a critical strategic metal by the United States and European Union. China is responsible for approximately 80% of annual worldwide production. There is currently only one magnesium metal producer in the US.

Magnesium Oxide (MgO) is a widely used industrial mineral with end uses in fertilizer, animal feed, and environmental water treatment as well as industrial applications primarily as a refractory material in the steel industry. The majority of refractory grade MgO used in the US and Canada is imported from China.

Qualified PersonThe technical portions of this press release have been reviewed by Allan Reeves (P. Geo.) of Tuun Consulting, Inc. and Andris Kikauka (P. Geo.), Vice President of Exploration for MGX Minerals.

Cautionary NotesMineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Mineral Resource estimates do not account for mineability, selectivity, mining loss and dilution. The Mineral Resource estimate stated herein includes Inferred material, which is normally considered too geologically speculative to have economic considerations applied, thereby to enable them to be categorized as Mineral Reserves. There is also no certainty that Inferred material will be converted to either the Indicated or Measured categories of Mineral Resources, through further drilling. Similarly, there is no certainty that Mineral Resources will convert to Mineral Reserves, once economic considerations are applied.
